I did. Knocked it down to 43%.After the bump map we now have this. You can adjust the opacity of the bump map to make it less noticeable if desired:
Awww, crap! I was blowing through the steps until we got to that dang histogram looking thing again...Merge down the difference layer, invert it, then bring up the layers dialog and adjust it to be a wider band of white on black. This will be used as the layer mask for the dirt….
NO idea what this means, so i just moved the three little arrows close together in the middle, kind of like Rob's example pic.
Not for me. I was surprised when nothing happened.Go back to the Dirt Layer and add a layer mask, using the “Land Mask” channel. Now right click on the layer mask and select “Apply layer”. This will erase everything that is not above the land.
